Description

Technical Field

[0001] This application relates to the technical field of water pumps, and in particular, to a portable lightweight water pump. Background Art

[0002] Currently, water pumps are important equipment for disaster relief. When in use, the entire unit of the water pump needs to be submerged in water, so as to use the water pump and the water hose to pump out the accumulated water.

[0003] Traditional disaster relief water pumps include a motor cylinder, an inlet section, and an outlet module with an impeller and a guide vane inside. One end of the inlet section is detachably connected to the motor cylinder through a flange and bolts, and the other end of the inlet section is detachably connected to the outlet module through a flange and bolts. During actual operation, since the staff needs to manually transport the water pump to a designated position for operation, a lifting mechanism needs to be provided on the water pump to facilitate the staff to lift and transfer the water pump. However, since the lifting mechanism cannot interfere with the normal use of the water pump, a cubic mesh structure is usually used to clamp the two flanges in the middle. By using two large-diameter flanges, the position of the mesh structure is limited, and then a lifting structure is provided on the mesh structure, so as to realize the manual lifting and transfer of the water pump by the staff.

[0004] However, since the diameters of the two flanges are large, they will have a large mass by themselves. At the same time, since the mesh structure needs to clamp and cover the two flanges completely, it means that the overall span of the mesh structure needs to extend from the flange between the inlet section and the motor cylinder to the flange between the outlet module and the inlet section, which will eventually lead to a large volume of the entire mesh structure and a large mass of the water pump. In the critical period of disaster relief, time is of the utmost importance. A water pump with a large mass is not convenient for the staff to lift and transport it to a designated position, affecting the efficiency of disaster relief, and there is room for improvement. Summary of the Utility Model

[0005] In order to make the water pump more precise, small and lightweight, this application provides a portable lightweight water pump.

[0006] A portable lightweight water pump provided by this application adopts the following technical solutions:

[0007] A portable lightweight water pump, comprising a motor cylinder and a water outlet module. A support structure is provided between the motor cylinder and the water outlet module. An inlet space is formed between the support structure and the water outlet module. The support structure is inclined and outwardly expanded in the direction from the motor cylinder to the water outlet module. The upper end of the support structure is detachably connected to the water outlet module, and the lower end of the support structure is fixedly connected to the motor cylinder. A lifting mechanism is clamped on the support structure, and an installation groove for hooking and cooperating with the lifting mechanism is provided on the support structure, and the opening direction of the installation groove faces the direction of the water outlet module.

[0008] By adopting the above technical solution, the upper end of the support structure is detachably connected to the water outlet module, and the lower end of the support structure is fixedly connected to the motor cylinder, so that the support structure is fixed between the water outlet module and the motor cylinder. At the same time, by using the installation groove provided on the support structure, the lifting mechanism clamped on the support structure can be stably embedded in the installation groove, greatly reducing the occupied space of the lifting mechanism and making it more convenient for the staff to lift and transport the water pump.

[0009] Preferably, a connecting member is integrally formed on the support structure, and the connecting member is detachably connected to the water outlet module.

[0010] By adopting the above technical solution, the detachable connection between the connecting member and the water outlet module facilitates the staff to disassemble and install the water outlet module as needed.

[0011] Preferably, a fixing bolt is provided on the connecting member. The fixing bolt passes through the connecting member from bottom to top and is threadedly connected to the water outlet module.

[0012] By adopting the above technical solution, the fixing bolt passes through the connecting member and is threadedly connected to the water outlet module, so that the water stains in the bolt holes will naturally drip under the influence of gravity after the water outlet module is disassembled after underwater operation, reducing the possibility of rusting of the fixing bolt during use.

[0013] Preferably, a first weight-reducing groove is provided on the connecting member.

[0014] By adopting the above technical solution, by using the first weight-reducing groove, the weight of the connecting member is reduced, making the connecting member lighter and more convenient for disassembly and installation.

[0015] Preferably, a second weight-reducing groove is provided on the support structure.

[0016] By adopting the above technical solution, by using the second weight-reducing groove, the weight of the support frame is reduced, further reducing the overall weight of the water pump and facilitating the staff to carry the water pump.

[0017] Preferably, the opening of the installation groove is inclined from the axis of the motor cylinder towards the direction radially away from the axis.

[0018] By adopting the above technical solution, being inclined from the axis of the motor cylinder towards the direction radially away from the axis makes it difficult for the support structure to slide out of the installation groove.

[0019] Preferably, the support frame is provided with a guiding surface inside the installation groove.

[0020] By adopting the above technical solution, the arrangement of the guiding surface inside the installation groove facilitates the installation and fixation of the lifting mechanism by the staff.

[0021] Preferably, the lifting mechanism includes an arc-shaped mesh cover which is clamped on the support structure. An adaptation groove is arranged along the circumferential direction of the motor cylinder, and the lower end of the arc-shaped mesh cover is embedded in the adaptation groove.

[0022] By adopting the above technical solution, the arrangement of the arc-shaped mesh cover clamped on the support structure enables the support structure in the installation groove to effectively support and fix the arc-shaped mesh cover. At the same time, the arrangement of the adaptation groove reduces the risk of the arc-shaped mesh cover sliding out of the installation groove due to force-induced shaking, thereby reducing the occupied space of the arc-shaped mesh cover and making the overall mechanism more compact, small and lightweight.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By detachably connecting the upper end of the support structure to the water outlet module and fixedly connecting the lower end of the support structure to the motor cylinder, the support structure is fixed between the water outlet module and the motor cylinder. At the same time, the arrangement of the installation groove on the support structure enables the lifting mechanism clamped on the support mechanism to be stably embedded in the installation groove, greatly reducing the occupied space of the lifting mechanism and making it more convenient for the staff to lift and transfer the water pump.

[0025] 2. By arranging the second weight reduction groove, the weight of the support frame is reduced, further reducing the overall weight of the water pump and facilitating the handling of the water pump by the staff.

[0026] 3. By arranging the arc-shaped mesh cover clamped on the support structure, the support structure in the installation groove can effectively support and fix the arc-shaped mesh cover. At the same time, the arrangement of the adaptation groove reduces the risk of the arc-shaped mesh cover sliding out of the installation groove due to force-induced shaking, thereby reducing the occupied space of the arc-shaped mesh cover and making the overall mechanism more compact, small and lightweight.

Detailed implementation manners

[0032] The following is a further detailed description of the present application in conjunction with the attached Figure 1 - attached Figure 3 to further illustrate the present application in detail.

[0033] The embodiment of the present application discloses a portable lightweight water pump.

[0034] Referring to Figure 1 and Figure 2 , a portable lightweight water pump includes a motor cylinder 1 and a water outlet module 2. A support structure 3 and a lifting mechanism 4 are arranged between the motor cylinder 1 and the water outlet module 2. The upper end of the support structure 3 is detachably connected to the water outlet module 2. An intake space is formed between the support structure 3 and the water outlet module 2. The support structure 3 includes a support frame 31. The support frame 31 is arranged in a circumferential array with the output shaft of the motor cylinder 1 as the axis. In this embodiment, three support frames 31 are provided. Since the structures and connection methods of the three support frames 31 are the same, one of the support frames 31 will be taken as an example for elaboration.

[0035] Referring to Figure 3 , the lower end of the support frame 31 is welded or integrally formed on the surface edge of the motor cylinder 1 close to the water outlet module 2. The support frame 31 is arranged to be inclined and outwardly extended along the direction from the motor cylinder 1 to the water outlet module 2.

[0036] Referring to Figure 3, at the upper ends of the three support frames 31, a connecting member 32 is welded together. The connecting member 32 is detachably connected to the water outlet module 2. The connecting member 32 is arranged in a circular ring shape. The diameter of the connecting member 32 is the same as the diameter of the lower surface of the water outlet module 2. The diameter of the connecting member 32 is larger than the diameter of the motor cylinder 1. The connecting member 32 is coaxially arranged with the water outlet module 2 and the motor cylinder 1. Bolt holes 321 and fixing bolts 322 are arranged in a circumferential array on the connecting member 32. Both the bolt holes 321 and the fixing bolts 322 are provided with six. Any fixing bolt 322 passes through the bolt hole 321 from bottom to top and forms a threaded connection with the water outlet module 2, which facilitates the staff to disassemble and install the water outlet module 2 as needed. At the same time, after the water outlet module 2 is disassembled after completing the underwater operation, the water stains in the bolt holes 321 will naturally drip under the influence of gravity, reducing the possibility of the fixing bolts 322 rusting during use.

[0037] Refer to Figure 2 , in other embodiments, by using the detachable connection between the connecting member 32 and the water outlet module 2, the water outlet module 2 can be replaced with a water outlet module 2 with a different lift.

[0038] Refer to Figure 3 , on the connecting member 32, six first weight reduction grooves 323 are arranged in a circumferential array along the axis of the motor cylinder 1. The arrangement of the first weight reduction grooves 323 reduces the weight of the connecting member 32, making the connecting member 32 lighter and more convenient for disassembly and installation.

[0039] Refer to Figure 1 and Figure 3 , at one end of the support frame 31 close to the connecting member 32, an installation groove 33 for supporting and fixing the lifting mechanism 4 is opened. The installation groove 33 is hook-shaped and the opening is inclined from the axis of the motor cylinder 1 towards the direction radially away from the axis, so that the support frame 31 is not easily slipped out of the installation groove 33; a guiding surface 331 is arranged in the support frame 31 within the installation groove 33. The guiding surface 331 is connected to the lower edge of the connecting member 32, facilitating the hook connection between the lifting mechanism 4 and the installation groove 33.

[0040] Refer to Figure 3 , on the side of the support frame 31 facing away from the installation groove 33, a second weight reduction groove 311 is opened, thereby reducing the weight of the support frame 31 and further reducing the overall weight of the water pump, facilitating the staff to carry the water pump.

[0041] Refer to Figure 3 and Figure 4, the lifting mechanism 4 includes two arc-shaped mesh covers 41 rotatably connected by hinges. When the two arc-shaped mesh covers 41 are closed, the hoop is on the three support frames 31. On one side of the motor cylinder 1 close to the support frame 31, an adaptation groove 11 is provided along its circumference. The upper edge of the two closed arc-shaped mesh covers 41 is embedded in the installation groove 33, and the lower edge of the two closed arc-shaped mesh covers 41 fits in the adaptation groove 11, thus ensuring the stable connection between the arc-shaped mesh cover 41 and the water outlet module 2. The two closed arc-shaped mesh covers 41 are arranged in an inverted cone structure, and the diameter of the two closed arc-shaped mesh covers 41 on the side close to the water outlet module 2 is always smaller than the diameter of the lower surface of the water outlet module 2, so that the installation groove 33 of the support frame 31 can effectively support and limit the arc-shaped mesh cover 41, reducing the risk of the arc-shaped mesh cover 41 slipping out of the installation groove 33 due to shaking caused by force, and at the same time reducing the occupied space of the arc-shaped mesh cover 41, making the water pump more compact and portable, and facilitating the staff to lift and transport the water pump.

[0042] Referring to Figure 4 , a lock 42 is provided at the connection of the two ends of the arc-shaped mesh cover 41, and the staff can quickly install or disassemble the arc-shaped mesh cover 41 through the lock 42. Pulling rings 43 are symmetrically arranged along the radial direction of the arc-shaped mesh cover 41, and any pulling ring 43 is rotatably connected to the arc-shaped mesh cover 41. The setting of the pulling rings 43 facilitates the staff to lift the water pump through the pulling rings 43, improving the convenience of use.

[0043] The implementation principle of the embodiment of the present application is as follows: During actual operation, when the staff needs to carry out handling operations on the water pump, the upper end of the arc-shaped mesh cover 41 is embedded in the installation groove 33, and at the same time, the arc-shaped mesh cover 41 is installed and fixed through the lock 42. Thus, the staff can use the pulling rings 43 on the arc-shaped mesh cover 41 to carry out handling operations on the water pump, improving the convenience of use.

[0044] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
